Answer:

Step-by-step explanation:

If triangle side lengths are an arithmetic sequence (have a common difference), they must have the ratios 3:4:5 to make a right triangle. Here, the ratios of the side lengths are 4:5:6, so will not be a right triangle.

"The product of a six and a number increased by four is equal to

NeTakaya

Answer:

$6x + 4 = 12x - 20$

$x = 4$

Step-by-step explanation:

Let "x" be the number.

Product of 6 and x (6*x), increased by 4 = $6x + 4$

Product of 12 and x, (12*x), decreased by 20 = $12x - 20$ .

Set both expressions equal to each other and solve for x as shown below:

$6x + 4 = 12x - 20$ (equation)

Subtract 12 from both sides

$6x + 4 - 12x = 12x - 20 - 12x$

$-6x + 4 = -20$

Subtract 4 from both sides

$-6x + 4 - 4 = -20 - 4$

$-6x = -24$

Divide both sides by -6

$\frac{-6x}{-6} = \frac{-24}{-6}$

$x = 4$
